| 25 /* A short introduction to the new Drag'n'Drop Model: | |
| 26 | |
| 27 A drop generates a extended misc-user-event, as defined in events.[ch]. | |
| 28 This event contains the same as a eval and a button event. | |
| 29 The function of a drop is set to 'dragdrop-drop-dispatch' which will be | |
| 30 defined in ../lisp/dragdrop.el. | |
| 31 The object of the misc-user-event has the following format: | |
| 32 ( TYPE . DATA ) | |
| 3025 | 33 TYPE is one of `dragdrop-MIME' and `dragdrop-URL' |
| 34 DATA - if TYPE is `dragdrop-URL', DATA is a list of valid URL strings. It | |
| 428 | 35 is always a list, also if only one URL string is within it. |
| 3025 | 36 - if TYPE is `dragdrop-MIME', DATA is a list of MIME elements. |
| 428 | 37 Each can be a string or a list. |
| 38 if it is a string it is the pure MIME data complete with header | |
| 39 and body. | |
| 40 if it is a list it should look like | |
| 41 ( MIME-TYPE MIME-ENCODING MIME-DATA ) | |
| 42 MIME-TYPE list of type and key.value conses. Same as in tm-view | |
| 43 MIME-ENC the same (a string in this case) | |
| 44 MIME-DATA is a string | |
